A classic two deck game of solitaire where you can only build on the foundation. Both variants are free to play. No in-app purchases.
There are 8 foundation piles, four build up from Aces and four build down from Kings. You cannot move cards on the tableau, only promote them to the foundation. More Cards deals one card to each tableau column (like Spider).
In the classic version you get one free shuffle. In the relaxed version you get three free shuffles.
